About keys & keystock

Parallel Key is listed under Keys & Keystock — square, rectangular, woodruff keys and keystock bar. Keys and keystock are essential mechanical components used to prevent relative rotation between a shaft and a rotating machine element such as a gear, pulley, or coupling. They transmit torque by fitting into keyways machined into both the shaft and the hub.
